Title: Production of magnetic recording medium
Inventor: MASUYA HARUKO
IPC: G11B5/65
Filed: 1982-08-30
Abstract: PURPOSE:To obtain high coercive force, high angular ratio and a low noise level by forming a magnetic layer with a columrar crystal consisting essentially of Fe and by an oblique vapor deposition process and then applying an etching process to said magnetic layer to improve the orientation effect of the magnetic layer. CONSTITUTION:A magnetic metal consisting essentially of Fe is obliquely vapor- deposited on a nonmagnetic supporter 1 made of polyimide, etc. to obtain a magnetic layer 2 in which a columnar crystal 3 is grown obliquely. Then an etching process is applied in a short time with an etching solution containing diluting liquids of hydrochoric acid, phosphoric acid and nitric acid, respectively. As a result, the crystal 3 can be set along the surface of a nonmagnetic matter having larger inclination than the vertical line of the surface of a magnetic material. This medium has an effect equivalent to the fact that the incident angle of vapor deposition is substantially increased. Then a top coating of a resin film is applied when necessary to the surface of the layer 2 to which a substantial orientation process is applied in order to increases the mechanical strength for adhesive intensity of the layer 2 as well as to aviod oxidation.

Title: Driving circuit for magnet
Inventor: YANAGIDA SHIYOUJI
IPC: B41J9/44
Filed: 1980-10-27
Abstract: PURPOSE:To reduce unevenness of an energy generated by the magnet by reducing exciting current by turning control current on before a signal to control the time length of the exciting current is turned off. CONSTITUTION:When a ham enable signal is turned on, analog switch 6 is turned off and current iM determined by reference voltage -Vref and resistances 7 and 8 flows to the magnet 4. Prior to the ham enable signal being turned off, an ICONT signal is turned on to turn a switch 5 off. At this time, the current iM is reduced to a value determined by the reference voltage -Vref and the resistance 8. When the ham eneable signal is turned off, the analog switch 6 is turned on and iM and the ICONT signal are turned off respectively, whereby the switch 5 is turned on. In this way, by connecting a series circuit composed of the analog switch 5 and the input resistance 7 in parallel to the input resistance 8 for the reference voltage -Vref of a conventional device, the current flowing at the time when the exciting current is put off can be reduced, whereby the effect of printing pressure due to the non-uniformity of the pulse width of the ham enable signal is reduced to enable thus printing of uniformity and excellent quality.

IPC: H04B1/50
Filed: 1986-06-25
Abstract: PURPOSE:To obtain a simultaneous call type cordless interphone capable of two-way calling by calling and paging through one talk switch, outputting an operational sound when the talk switch is operated and stopping the outputted operational sound when an operator receives a carrier signal from the other party. CONSTITUTION:The talk switch 11 is a so-called pushbutton, and a timer T1 is set when the operation is released. This means that the timer T1 is so constituted as to be set when an input signal rises. A calling tone generation part 106 is operated only when there is no detection of a carrier signal and when the talk switch 11 is operated(after the release of the operation, during one hour, that is, the set time tau of the timer T1), and a calling tone is transmitted to a transmission circuit part II. An AND gate 2 has such constitution as to operate an operational sound generation part 104 due to the AND between the output of the talk switch 11 and that of a NOT gate. Only when the talk switch 11 is operated and no carrier signal is detected, the operational sound is outputted from a speaker SP.
